so what, the 4 (for Sony at least) post-launch are Hawkeye, Spider-Man, T'Challa and... I could see them throwing in Scarlet Witch for another woman, plus someone else with like, AoE ranged combat. As far as a set of 9 goes... I mean, there are worse rosters you could run.
That being said, if they don't run a Defenders off-shoot story pack in like, 12 months where you can grab DD, IF, JJ and LC as a set package with some group story mission content around NY post A-Day or whatever, then they fukking all the way up. Game style literally made for that exact B-story
